What's happening?

Okay so I'm 15dpo AF was supposed to show up yesterday I took a test at 12dpo and it was negitive .... I had cramps like AF was coming all week but then they just stopped yesterday... and tracking my bbt on the 22nd my temp droped so I was sure she was going to show but today I took my temp and it's back up and no sign of her.... I'm so confused if I am pregnant I don't feel like it at all, like there is 0 symptoms. Should I test again or wait till AF is a week late?
